Mono Compatibility is Broken or Non-Existent?

[suicvne]

First, some system background. I'm running Debian 8.1 w/ KDE 4.14. MonoDevelop 5.9.4, the latest Mono from the Mono repositories (NOT Debian's) and the following Mono packages installed: mono-complete, mono-xsp, mono-xsp4. This is enough to get a simple sample up and running. The code sample is as follows (.NET console project in MonoDevelop, targetting "Mono/.Net 4.5"):
Output of mono --version:

I pull the latest IF.Lastfm from the official Nuget gallery in MonoDevelop.

using System;
using IF.Lastfm.Core.Api;
using IF.Lastfm.Core.Objects;

namespace LastfmTest
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            Console.WriteLine ("Hello World!");

            var lastfmClient = new LastfmClient ("", ""); //I put my proper keys in here of course
            var response = lastfmClient.User.GetRecentScrobbles ("mrmiketheripper", null, 0, 1);
            LastTrack lastTrack = response.Result.Content [0];

            Console.WriteLine ("{0} - {1}", lastTrack.Name, lastTrack.ArtistName);

            Console.ReadLine ();
        }
    }
}

Everything builds and compiles okay, but when I run it, literally nothing happens. My initial "Hello world!" isn't even shown.

I'm confused as to what's going on here. No errors shown or anything. Surroudning the code in a try-catch produces a similar result.

So you don't see "Hello world!" in the console window... this doesn't look like it's related to the library. Are you able to step through the code with the debugger?

I can't try out your setup right now, but I can test with my Ubuntu VM on Monday.

Re: general mono compatibility, I think @Zumicts has sucessfully run the library under Android, and I've used it under Mono on an Ubuntu server recently.

If you're not getting the hello world the issue might be something else. Could you remove last.fm and just run the hello world?

[suicvne]

Removing last.fm and just running the hello world produces no problems. @Zumicts

😕 I'll try and reproduce.

@rikkit thank you!

@luigifan Just got back from holiday, sorry I didn't get a chance to test before I went.

I've tried to reproduce on Ubuntu 14.10 and I can't. I followed the setup instructions here. Then I installed mono-devel. Opening the solution, I found that the IF.Lastfm.Core project compiled fine, though checking the references I noticed that MonoDevelop "couldn't find .NETPortable subset" framework 4.5, profile 269, and I wasn't able to reference IF.Lastfm.Core from a new command line project. So I installed the referenceassemblies-pcl package - it's in the install notes but I missed it at first. The test program then worked (after restarting MonoDevelop).

MonoDevelop didn't complain when referenceassemblies-pcl wasn't installed, so that makes me think this could be the problem. Can you check if you have that installed?

[suicvne]

@rikkit I will verify this right now. Who's that guy who has such a good taste in music though? ;)

[suicvne]

@rikkit I installed referenceassemblies-pcl and i'm still getting the same results where it just idles, not even a hello world. This is really weird.

[rikkit]

Okay. So now the difference between our tests is that yours uses Nuget whereas I'm building from source... could be something wrong with the NuGet package? 😕 I'll test that tonight.

[suicvne]

@rikkit okay thank you! if i have time today I will test from source
